PUP has been in place since start of the pandemic
The state is still owed €19m in pandemic unemployment payments (PUP) that were wrongly given out.
There have been about 15,000 overpayments under the scheme.
The PUP was introduced in March 2020, when strict restrictions were first introduced.
It remains capped at €350 a week for those losing their jobs in hospitality.
872,000 people have received at least one payment under the scheme - with 58,000 having their claims refused.
Claims have also been withdrawn from about 141,000 people.
The Department of Social Protection says there have been about 15,000 overpayments so far.
These are valued at €29m and latest figures show only €10m of that has been repaid.
The department says all cases of suspected fraud are investigated by its special investigation unit, which includes 21 gardai.
